ように、耐圧層２を構成する扇形の異形線にある。In this structure, 1 is a fiber optic unit, 2 is a fiber optic unit, and in order to protect the fiber optic unit from the sea pressure of the deep sea (for example, 800 atm in the deep sea of 8000 m), three deformed lines 11, 12, 13 with a fan-shaped cross section are combined. A pressure-resistant layer, 3 is a piano wire which is a tension member of an optical fiber cable, 4 is a metal tube for fixing the piano wire, and 5 is an insulating layer made of plastic or the like. Between the unit and the pressure resistant layer, and between the pressure resistant layer and the metal tube, there is filled a compound for preventing water running which occurs when a failure occurs in the optical cable.

が必要である。(Function) The pressure resistant pipe of the cable for the submarine optical fiber has a tensile strength of 12
6 Kg f / mm 2 or more, preferably 130 Kg f / mm 2 or more is required. The strength of the steel wire is determined by the strength of the material and the cold working amount, but according to the study by the present inventors, for example, in order to manufacture the deformed wires 11 to 13 shown in FIG. Is required to be 85% or less in order to suppress the occurrence of work cracks. In order to obtain a product strength of 126 Kg f / mm 2 with a cold working rate of 85% or less, the wire material must have a tensile strength of 70 Kg f / mm 2 or more.

して添加することが望ましい。Further, the above materials are required to have excellent strength and toughness at the welded portion. Generally, the weldability tends to deteriorate in proportion to the C content, but in order to satisfy the tensile strength of 70 Kg f / mm 2 or more,
It is desirable to add an appropriate amount of C and replace Mn or a part of Mn with Cr in a possible range.
このように本発明においては強度、溶接性及び加工性を
満足するために、特定の成分元素を添加するものである
が、以下に成分元素の添加範囲を上記のように限定した
理由を説明する。Thus, in the present invention, in order to satisfy the strength, weldability and workability, a specific component element is added, but the reason for limiting the addition range of the component element as described above will be described below. .
Ｃは溶接性の点から低い方が望ましいが、0.3％未満で
は70Kg f/mm2以上の強度は得られない。一方、0.65％超
では溶接部の靭性、加工性が劣化するので、0.3％〜0.6
5％とする。From the viewpoint of weldability, C is preferably low, but if it is less than 0.3%, a strength of 70 Kg f / mm 2 or more cannot be obtained. On the other hand, if it exceeds 0.65%, the toughness and workability of the weld will deteriorate, so 0.3% to 0.6%
5%
Siはその固溶体硬化作用によつて線材を強化するために
添加されるが、１％を超えると靭性を劣化させるので１
％を上限とした。Si is added to strengthen the wire rod by its solid solution hardening action, but if it exceeds 1%, the toughness deteriorates, so 1
% Was set as the upper limit.
Mnは溶接性への影響が少なく、強度を増加させる元素で

70Kg f/mm2以上の強度を得ることもできない。一方1.5
％超では線材の焼入性が高くなりすぎて、溶接部に熱処
理後マルテンサイトが発生し、加工性を著しく劣化させ

た。Mn is an element that has little effect on weldability and increases strength, and it is desirable to add Mn within a possible range. Mn 0.2%
If it is less than S, S cannot be fixed as a sulfide, and
It is not possible to obtain a strength of 70 Kg f / mm 2 or more. While 1.5
%, The hardenability of the wire becomes too high, and martensite is generated in the welded portion after heat treatment, which may significantly deteriorate the workability, so the addition range was limited to 0.2% to 1.5%.
CrはMnと全く同じ作用を持つ元素で、Mnの一部と置換し
て添加することが出来るがMnとCrの合計量が1.5％を超
えると、溶接部に熱処理後マルテンサイトが発生するの
で、Cr1.3％以下、Mn＋Cr1.5％以下に添加量を限定し
た。Cr is an element that has exactly the same action as Mn, and it can be added by substituting a part of Mn, but if the total amount of Mn and Cr exceeds 1.5%, martensite will occur in the weld after heat treatment, so , Cr 1.3% or less, and Mn + Cr 1.5% or less.

Ｐ、Ｓはいずれも不純物としてみられるが、靭性の点か
らそれぞれ0.03％以下にすることが望ましい。またＮは
時効脆化を抑制するために0.01％以下に抑えることが望
ましい。Both P and S are seen as impurities, but from the standpoint of toughness, it is desirable to make each 0.03% or less. Further, N is preferably suppressed to 0.01% or less in order to suppress age embrittlement.
線材の強度は と、線材のオーステナイト域からの冷却速度によつて決

ことが明らかになつたので、Ceqを0.57％以上に限定し
た。これはCeqが0.57％より低い線材を強度を上げるた
めに、高速冷却すると加工性に致命的なマルテンサイト
が現われるためである。The strength of the wire According to the cooling rate from the austenite region of the wire, the higher the Ceq and the higher the cooling rate, the more the strength increases. Since it was revealed that a ferrite / pearlite steel wire rod having a strength of 70 Kg f / mm 2 or more could not be obtained even if it was cooled with, the Ceq was limited to 0.57% or more. This is because martensite, which is fatal to workability, appears when high-speed cooling is used to increase the strength of wire rods with Ceq lower than 0.57%.
本発明の異形線用線材は、常法により線材圧延されて調
整冷却された後溶接されて長尺線材とされ、更に溶接部
を熱処理して整粒された微細なフエライト・パーライト
組織とされ、更に冷間伸線または冷間圧延により所要サ
イズとされる。The deformed wire rod of the present invention is a long wire rod which is rolled and adjusted and cooled by a conventional method and then welded to be a long wire rod. Furthermore, the required size is obtained by cold drawing or cold rolling.
線材の溶接は強加圧アツプセツト方式、TIG方式あるい
はレーザー方式等を用い、格別限定されないが、例えば
強加圧アツプセツト方式は、最初比較的低電流密度（〜
75A/mm2）で通電を開始する。継手が軟化し、初期加圧

強加圧力（〜50Kg/mm2）を加える。あとは加圧力と軟化
部が追出されていつた後の抗力とのバランスで停止する
と良い。Welding of wire is performed by using a high pressure upset method, TIG method, laser method, or the like, and is not particularly limited. For example, the high pressure upset method is a relatively low current density (~
Start energizing at 75A / mm 2 ). The joint softens and begins to deform under the initial pressing force, and at the same time the current is stopped and a so-called strong pressing force (up to 50 Kg / mm 2 ) is applied. After that, it is better to stop by the balance between the pressing force and the drag force after the softened part is being expelled.

度を有するフエライト・パーライト組織にするのがよ
い。Here, in the welded part, the abutting part and the heat-affected part in the vicinity thereof are heated to A 1 point or more and then rapidly cooled. Therefore, as-welded, the welded part has a martensitic structure with a Vickers hardness of 600 or more, and therefore has a markedly poor ductility. Therefore, in order to improve the workability from the wire rod to the deformed wire, it is preferable to form a ferrite / pearlite structure having the same strength as the base metal by a heat treatment of heating and cooling the welded portion to an austenite region.
即ち、本発明の異形線は、最終リダクシヨンが80％以上

つて整粒されたフエライト・パーライト組織にすること
が好ましい。That is, the deformed wire of the present invention is often formed into a deformed wire by undergoing die drawing in which the final reduction reaches 80% or more and roll flat rolling, so cold workability is required. Therefore, the wire structure of the present invention is preferably a ferrite-perlite structure in which the wire is sized over the entire length by the controlled cooling in the hot rolling process or the patenting treatment after rolling.
光フアイバー用異形線は、例えば7mmφ線材をダイス引

行い、第２図に示すように内径a3.0mm、外径b6.0mm、厚
みt1.5mmの異形線11〜13をうることができる。For the deformed wire for optical fiber, for example, a 7 mmφ wire rod is die-drawn to 4.3 mm and flat-rolled with a roll to form a 2.3 mm-thick rectangular wire rod. Then, die drawing is performed to make it substantially fan-shaped, and as shown in FIG. 2, the deformed wires 11 to 13 having an inner diameter of a3.0 mm, an outer diameter of b6.0 mm and a thickness of t1.5 mm can be obtained.
なお、異形線の本数としては、第１図及び第２図で円形

が、これにこだわるものではなく、耐圧層の大きさなど
に応じて、複数本の分割扇形とすることができる。な
お、工業的見地からは２〜10本程度が望ましい。As for the number of modified lines, the shape in which a circle is divided into three substantially fan-shaped shapes is shown in FIGS. 1 and 2, but the shape of the breakdown voltage layer is not limited to this. According to the above, a plurality of divided fan shapes can be formed. From an industrial point of view, it is desirable that the number is 2 to 10.

が梨地状を有するように限定した理由を述べる。FIG. 1 shows an example of the structure of the pressure resistant layer of the submarine optical fiber cable manufactured by using the modified wire of the present invention. In the figure, 11, 12, and 13 are modified lines with a fan-shaped cross section.
The part of is indicated by a dashed line. Here, the outer peripheral surface 21, the inner peripheral surface 22 and the side surface 23 of the irregular line are satinized as shown by the spots in FIG. The reason why the surface of the modified line is limited to have a satin finish will be described below.

〜13の外周面21と内周面22に梨地加工が施されている
と、コンパウンドとの間の摩擦係数が増し、水走り防止
性が向上する。When a failure occurs in the submarine optical cable for some reason, the gap between the optical fiber unit 1 and the pressure resistant layer 2 or the pressure resistant layer 2 and the metal tube 4 shown in FIG. Therefore, damage occurs in a long section of the cable. Therefore, normally, such voids are filled with a compound to prevent water running. Here, as shown in FIG.
When the outer peripheral surface 21 and the inner peripheral surface 22 of Nos. 13 to 13 are subjected to satin finish, the coefficient of friction with the compound is increased and the water running prevention property is improved.
また、異形線11〜13の側面23が梨地状に加工されている
と、異形線を組み合せて耐圧層を構成したとき、異形線
相互の接合面の密着性が増し、耐圧層の構造安定性が増
す。Further, if the side surfaces 23 of the deformed wires 11 to 13 are processed to have a satin finish, when the deformed wires are combined to form a pressure resistant layer, the adhesiveness of the joint surface between the deformed wires is increased, and the structural stability of the pressure resistant layer is improved. Will increase.

どによつて付与される。This satin is uneven with a depth of about 0.002 to 0.03 mm, and is applied by performing a satin finish on the roll surface in the final step of the profile wire manufacturing process, or by subjecting the surface of the profile wire to a shot blast process.
また、この異形線は、Ｎによる時効が有効に作用する15
0℃以上で、且つ鋼線の軟化が顕著にならない500℃以下
の温度時効することが、耐力の増加に有効である。In addition, the aging due to N acts effectively on this modified line 15
Aging at a temperature of 0 ° C or higher and 500 ° C or lower at which the softening of the steel wire is not remarkable is effective for increasing the yield strength.
